Lower and upper rails 2|, 22 respectively'are permanently and rigidly attached to the body 8 and extend throughout the length thereof. The lower rails 2| which are formed integral with each other, are secured to the apron walls 20 and to the lowermost portion of the carrier body 8, and the upper rails 22 are attached to the lower outer portions of the side apron walls l9. A

.pivot pins 35 and having material delivery chute 23 is slidably suspended from each set of rails 2|, 22 by means of lower andupper beads 24, '25 secured to each chute, and each of the chutes 23 is provided with a .handle '26 for facilitating sliding of the chutes along the rails. Each chute 23 is of such size that it may be brought into registry with the apron walls I9, 20 of the adjacent openings I5, and when so positioned, the corresponding walls I3, 20 and the lower wall 2! of the delivery chute will be in approximate alinement with each other.

The chutes 23 may also be provided with end pins 28 and with medial latch hooks 29 for eifecting detachable attachment of short or long 'As illustrated in Figs. 1 and 2, the short spout '30 is provided with end hooks 32 which are cooperable with the end pins 28 of the chutes 23, and the latch hooks 29 of the chutes 23 are cooperable with a transverse retainer 33 secured to the upper end of the spout provided with a similar attaching'means, and the short spout 3B is preferably additionally provided with a swing gate 34 secured thereto by a manipulating handle 36 as illustrated in Figs. 1 and 2. Additional spouts 3| of Various lengths may also be provided so as to-permit spouting of the material a considerable distance from the truck 5, and the spouts 30, 3| may be hung at the rear of the assemblage when not in use. Most of the parts of the material transporting and delivery assemblage may be formed of sheet metal riveted or welded together, and the rails 2|, 22 may be pro- ,vided with suitable lubricant such as grease to insure easy sliding of the chutes 23 therealong. During normal use of the improved assemblage, while the body 8 is being loaded with material and when the load is being transported from place to place, the body is lowered so as to cause the side beams I I to engage the lower frame 6, and the delivery chutes 23 are then confined between and are protected by the side beams of the frame 6. All of the openings l5 are in closed position as shown in Fig. 1, and the levers I! are so formed that they will clear the'side beams of the frame 6 and will permit beams H to rest upon the frame 6 without obstruction.

When it becomes desirable to discharge the contentsrof. one of the compartments formed by the partitions l2; such delivery may obviously be eifected from either side of the vehicle or truck 5. The body 8 may then be elevated with the aid of hydraulic hoists Ill to the position shown in Fig. 3, whereupon the chute 23 should be positioned adjacent the opening l5 from which delivery of material is to be eifected. An appropriate delivery spout30, 3| should then be applied to the delivery chute 23, and if the load is to be delivered in successive batches into baskets or other receptacles, a short spout 30 will be utilized, whereas for direct delivery of the load to a bin or manhole would necessitate the use of one or more long spouts 3| as illustrated in Fig.3. After the chute 23 and directing spout have been properly associated with the opening l5 through which delivery is'to be effected, the corresponding levers I! may be manipulated to withdraw the closure plate l6 more or less depending upon the desired rate of delivery. Such uncovering of the opening l5 will cause the material to gravitate through the opening and along the apron wall 20 and bottom 21 of the delivery chute, and the material will thereafter flow by gravity along the spout 30 or 3| which is attached to the chute 23. By virtue of the fact that the openings 5 extend upwardly from the lowermost portion of the bottom walls l3, that is, from the intersection line 4, the entire charge, from each compartment may obviously be readily delivered from such compartment by gravity, and

the opposite inclination of the bottom walls l3: toward the intersection line M will obviously prevent material from bridging over the discharge openings l5. When the desired quantity of material'has been discharged from any of the compartments, the closure'plate l6 may again be moved to closed position by manipulation ofthe corresponding lever l1, and further delivery of material will then cease. It is also to be noted that delivery of the material may be effected from either side of the truck 5 and from any of the several compartments, independently of all others, and the chutes 23 are conveniently slid- I able into a position of cooperation with any of the corresponding discharge openings I 5. i

From the foregoing detailed description it will be apparent that my present invention provides an improved structure and system for effecting universal delivery of material from a multiple compartment truck body, in any desired direction and from any desired compartment of the body.

for permitting delivery of batches of material to baskets or similar receptacles. The formation of the bottom walls l3 and the provision of openings l5 therein extending upwardly from the intersection line H of the walls I3, is of considerable importance since it not only makes it possible to deliver all of the material by gravity, but such formation also prevents bridging of the material across the openings I5. The attendant is therefore able to deliver all portionsiof the load with- I out crawling to the top of the body 8 and breaking upthe charge which would otherwise tend to bridge across the discharge openings. The entire assemblage is obviously simple and compact in construction besides being durable and readily manipulable, and the invention has proven highly successful in actual commercial use.

It should be understood that it is not desired to limit this invention to the exact details of construction or to the precise mode of use, herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.

I claim:

1. In combination, a material confining and transporting body having oppositely inclined intersecting bottom walls each provided with several material delivery openings extending upwardly therealong from the line of intersection, and a discharge chute movable horizontally along the exterior of each of said walls and being interchangeably communicable with the corresponding openings, each of said discharge chutes having its bottom in approximate alinement with the opposite bottom wall of the body.
